Samsung to take ARM Cortex-X to 2nm

Samsung to take ARM Cortex-X to 2nm

Samsung Electronics is developing a version of the ARM Cortex-X CPU core on its Gate-All-Around (GAA) process technology.

The collaboration sets the stage for a series of announcements and planned innovation between Samsung and ARM. The companies have plans to use the 2nm GAA process for next-generation data centre and infrastructure custom silicon, as well as an AI chiplet for mobile computing.

“As we continue into the Gen AI era, we are excited to extend our partnership with Arm to deliver the next generation Cortex-X CPU, enabling our mutual customers to create innovative products,” said Jongwook Kye, executive vice president and head of Foundry Design Platform Development at Samsung Electronics. “Both Samsung and Arm have built a solid foundation from many years of collaboration.  This unprecedented level of deep design technology co-optimization has resulted in a ground-breaking accomplishment, providing access to the newest Cortex-CPU on the latest GAA process node.”

“Our longstanding collaboration with Samsung has delivered multi-generation, leading-edge innovation,” said Chris Bergey, SVP and GM of the Client Business of Arm Inc. “Optimizing Cortex-X and Cortex-A processors on the latest Samsung process node underscores our shared vision to redefine what’s possible in mobile computing, and we look forward to continuing to push boundaries to meet the relentless performance and efficiency demands of the AI era.”

Samsung announced initial production of 3nm Multi-Bridge-Channel FET (MBCFET) using GAA technology back in 2022 as the successor to FinFET designs. This improves power efficiency with reduced supply voltage level, and enhanced performance with higher drive current capability.  The GAA implementation approach with nanosheets structure delivers maximum design flexibility and scalability. 

ARM optimised its latest Cortex-X CPU with additional performance and efficiency improvements for GAA using design-technology co-optimization (DTCO), which has been a critical factor to maximize the benefits for both the next generation Cortex-X CPU design architecture and GAA process technology.

Samsung sees this as accelerating access to the optimized implementation of the next generation Cortex-X CPU on custom chips.;
